He is a donking fish i had a earlier hand with that he played almost the same he is a very aggresive guy.What do you think my raise should be here?I don't have a decent sample size here so no stats.I'm never folding to his donks anyway.Thanks.

Although him minbetting is not exactly a check, it is like a check when it comes to pot size considerations so I would just raise to the size I would have bet vs a check, probably around 9. This leverages stacks and still doesn't commit you.
